Application filed April 28,

To all whom it may concern:

Be it known that I, JOSHUA B. HALE, a citizen of the United States, and resident of the city of Providence, in the county of Providence and State of R-hode Island. have invented certain new and useful Improvements in Braiding-Machine Carriers, of which the following is a specification.

This invention relates to braiding machine carriers, and has for its object to provide in such a carrier a lon yarn take-up arm pivoted on one side of t e thread-mass and arranged to control the let-oil mechanism, its free end extending to the opposite side of the mass and adapted to engage the supply yarn and serve as a take-up for the same.

The nature and advantages of the invention will be better understood when the following detail description is taken in connection with the accompanying drawings, the invention residing in the combination and arrangement of parts as claimed.

In the drawings forming part of this specification, like numerals of reference indi cate similar parts in the several views and wherein Figure 1 is a side elevation partly in sec-- tion illustrating the operation of my improved carrier.

Figure 2 is a plan View sectioned through the frame, on line 2-2 of Figure 1, showing the ratchet-toothed thread-mass supporting disk as engaged by the let-off pawl.

Figure 3 is a perspective view illustrating the hoop form of take-up arm.

Figure 4 is a section through the frame on line 44 of Figure 1,looking in the direction of the arrow.

Figure 5 is a perspective view of the letoff pawl.

With reference to the drawings. 10 designates the guiding base portion of the carrier. which engages the raceway of the machine. mounted on which guide is a central thread-mass supporting post 9 provided with a guide eye 8 at its upper end. and also mounted on this guiding base is a frameportion 11 which in the present case. comprises a sheet metal strip, the forward end of which is turned to extend upward providing a yarn guide standard 12 which is provided with aguide-eye 13 at its upper end and a second guide eye 14: near its middle. The

1920. erial No. 377,195.

guide eye is slotted as at 15, which slot extendsdownward and into the laterally-extending portion 16 of this plate for the pun pose presently described.

The rear end of this frame portion is also turned to extend upwardly providing a bearmg member 17, the sides 18 of which, see Figure 2, are turned forwardly providing bearing walls.

Between these side bearing walls I have mounted a pawl member 19 on the pivot 20, its lower end 21 being provided with pro- JGCUOHS 22 adapted to engage the ratchet teeth 23 on the thread supply supporting disk 21- and are normally pressed into engagement with said ratchet teeth by the coil spring 25.

At the upper end of this rear bearing member I have pivotally mounted at 26 the rear end 27 of the take-up lever arm 28, which arm is preferably formed from a strip of sheet stock bent into hoop form having a rearwaidly-extending loop portion 27 which is provided with pivot eyes 29 through which the above-mentioned pivot pin 26 passes.

These hoop-shaped arms 28 are adapted to encircle or extend around the opposite sides of the thread mass. which latter is indicated by dotted lines at 30 in Figure 1. and the forward end of this hoop is provided with a forwardly-projecting neck portion 31 which is adapted to extend through the slot 15 in the standard 12. and the end of this neck is provided with a guide eve 32through which the thread 33 is passed for the purpose of taking up or providing a tension on the same.

Between the side arms of this forwardlyextending neck portion. l have positioned a downwardly-extending plate 34 which. when the free end of the take-up is in its extreme low position. is arranged to extend through the lower portion of slot 15 into position to engage the stop motion on the machine (not shown) to arrest the action of the braiding machine.

In order to exert a tension on the yarn by causing a downward pressure on the free end of this lever, I have mounted a coil spring 34 on the pivot pin 26 one end 35 of which is caused to engage the arm of the lever 28 while its opposite end 34 engages the yarn-mass to rotate and supply more yarn, when the free end of the-take-up arm 1 threadniass, means one of the notches 37 in one of the side walls 18 of the aforesaid rear bearing member 17, the tension on which spring may be ad'usted by shifting the end 36 into the di erent ratchet teeth 23 of the plate 24 to release israised a predetermined distance.

My improved braider carrier has many advantages over the carrier of the ordinary construction, among others being: first, it is provided with a take-up arm of extreme length that is, the arm is pivoted on one side of the thread-mass while its thread-engaging end extends across to the opposite side of the mass and as the tripper finger is posi' tioned on thisv lever adjacent its pivoting point the force applied to the take-up end of this lever, required to operate the let-ofli' through the tripper finger is reduced to the very minimum: Second, another advantage is that by this construction the operating spring acts at the pivoting point of this long arm, whereby the movement of this arm causes the minimum amount of variation in 'the' tension on this spring during a stroke I produced.

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible. the invention being defined and limited only by the terms of the appended claims.
